The Calypso Bean (Phaseolus vulgaris) is a dramatic and beautiful bean. It is also called a Ying Yang bean because of the stark contrast of black and white that flows along the bean's length. About 3/8 inch long with a silky smooth texture and mild flavor, this bean is sure to look great on any plate. Calypso Beans are a delicious addition to pasta, salads, soups, casseroles and stews. Cooked Calypsos combined with cooked rice make a wonderful stuffing for vegetables.
